Common veno-venous extracorporeal membrane oxygenation configurations. (a) Conventional veno-venous extracorporeal membrane oxygenation, where the tip of the drainage cannula lies at the inferior vena cava-right atria junction and the tip of the return cannula is in the right atrium. (b) Femoral-femoral veno-venous extracorporeal membrane oxygenation, where the tip of the drainage cannula is in the infrahepatic inferior vena cava and the tip of the outflow cannula is in the right atrium. (c) The Avalon Elite^® veno-venous extracorporeal membrane oxygenation cannula, with bicaval drainage ports and a return port that directs oxygenated blood toward the tricuspid valve
